AP7361C-28D-13 is a linear regulator for power management. It possesses a high output voltage accuracy (±4% over full temperature range) and low dropout voltage, which makes it well suited for mobile and battery-powered systems. The device provides programs and DC/DC converter control functions, flexible compensation and few external components, making it ideal for high-efficiency, high performance and low-power applications.

AP7361C-28D-13 voltage regulator features include low dropout voltage, low quiescent current, fast transient response and excellent power supply rejection ratio (PSRR). It operates from an input voltage range of 4.5V to 28V and provides a fixed voltage output of 1.8V, 2.5V, 3.3V, 5.0V or any other output voltage in the range. It is available in a TO-263 package and requires a minimum of external components, such as an input bypass capacitor and an optional output capacitor, for the high-voltage, low-power linear regulator.

In terms of application field, the AP7361C-28D-13 is commonly used in power management of a wide range of devices. This includes digital products requiring voltage regulation, such as servers, notebooks, tablets and PDAs, as well as consumer, automotive and lighting applications. The device offers tight line/load regulation, low quiescent current, reverse battery protection and thermal foldback for circuit protection, making it an ideal solution for battery-powered systems.

The working principle of the AP7361C-28D-13 is fairly simple. It operates by comparing an internal reference voltage to a voltage across a feedback network. This network consists of a resistor divider, connected between the output and the reference pin. If the output voltage drops below its programmed value, the regulator will drive the output lower, until the reference voltage and the feedback network\'s reference voltage are once again equal.

In addition, the AP7361C-28D-13 regulates the output voltage by sensing the voltage difference between the ground and the error amplifier\'s inverting input, known as the zener voltage. This zener voltage is used to adjust the output voltage such that the error amplifier\'s output is equal to the reference voltage. regulate the output voltage.

In terms of performance, the AP7361C-28D-13 features a power output range of 0.2A to 3A and a 5℃/W thermal resistance. It also features low dropout voltage, fast transient response and excellent power supply rejection ratio (PSRR) for improved system stability and efficiency.

Overall, the AP7361C-28D-13 is a linear regulator for power management which provides programs and DC/DC converter control functions, flexible compensation and few external components. It is widely used in consumer, automotive and lighting applications, as well as in digital products requiring voltage regulation. A key feature includes its low dropout voltage, low quiescent current, fast transient response and excellent power supply rejection ratio.
